Application filed October 11, 1926. Serial No. 140,912.

The accompanying drawings, referred tov herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to ex- `plain the prineiplesofthe -invention.

In the accompanying drawings Figure l 1s a longitudinal vertical .sectional view through a plucklng machine disl closing an embodiment of the invention, said section being takenapproximately on line 1 1 of Figure 2.'

Figure 2 is a side view of the structure Figure 3 isa sectional view through Figure 4 on line 3 3.

o Figure- 4 is a sectional view through Figure 3 on line 4 4.

Figure 5 is a fragmentary sectional view through Figure 3 on line 5 5. A

Figure 6 is 'an enlarged fragmentary elevation illustrating a. control arm and associated parts. f The inventionis directed to producing a novel and'improved machine for plucking all the feathers from fowls with speed, eiiiciency, and safety to the operative; a machine having a positive. certain and speedy action, removing all feathers from the smallest' to the largest, and having a very large simultaneous operative extent and rapid recurrence of the successive plucking operations.

With these and other objects in view the invention comprises primarily a traveling chamber with one or more openings therein, through which a strong current of air is drawn inwardly, and feather gripping devices mounted at the opening to travel with the chamber and to grip and pluck the feathers drawn into the opening by the air current: the feather gripping means also preferably cutting oif the air suction through the opening as the feathers are gripped and plucked. The plucking and air controlling means preferably includes a cover adapted to open and close the opening in the travelling chamber, thereby gripping the feathers against the edge of thc opening and cutting of the air current as described; the gripping means, whether in the cover form, or otherwise, preferably` closing from within thel chamber outwardly as a safeguard for the hands of the operator. i

The travelling chamber is preferably pro- -vided with la plurality of the openings and feather gripping and suction controlling devices, the air being drawn into one of these' openings, and out throughanother, the operation at the air in-taking opening being already described, the gripping means at the Aother or air emltting openings to release the plucked feathers.

In the present preferred and herewith exemplified embodiment. the air chamber is rotatively mounted with a plurality of air openings in its periphery, there being a door hingedat each of these openings, and

located within the cylinder, the door cooperating with the edge` of the opening, to grip the indrawn feathers, and to substantially close the opening against the air suction. An approximately oppositely located opening has its door timed to open substantially concurrently to release the plucked 1 l feathers which are carried away by the air current.

Other features and objects of the invention will be primarily set forth in connection with the following detailed description; and

it will be understood that the preceding general description andthe following detailed description are explanatory and exemplary ofthe invention, but are not restrictive thereof.

Referring to the accompanying drawings by numeralsl` 1 indicates a casing which may be sheet metal and may be braced in any desired manner. vThis casing is formed with what may be termed a fan chamber 2, a suction pipe or chamber 3 and a discharge member 4. A fan 5 is mounted in chamber 2 and is rigidly secured to shaft 6 which is journaled in the casing 1""and which at one endhas a pinion 7 rigidly secured thereto and at the other end is connected with the rotating element of the motor 8. Pinion 7 meshes with' a large gear '9 which is rigidly the casing 1 and having rigidly secured thereto a sprocket wheel 11 accommodating the chain 12, which chain also passes over a Ais sprocket wheel 13 rigidly secured to the sha-ft 14. The shaft 14 is formed with a hollow section 15, (Figure 3) at the inner end, said hollow section being rigidly'secured to the rotating drum 16 through the clamping set screw 17. A reduced' extension 18 of the shaft 19 tits in the hollow section 15. The shaft 19 extends through the opposite end of the drum 16 to section 15 and has secured thereto an arm 20 provided with a spring pressed pin 21 adapted to be itted into any of the notches 22 in the plate 23. Plate 23 is secured to the casing l and is, consequently, stationary, so that the shaft 19 may be locked in different positions for purposes hereinafter fully described. A wheel 24 of rubber, bakelite or other material is rigidly secured in any desired manner to the .section 15 so as to rotate therewith, said wheel acting as a bumper for the swinging clamping members 25. The drum 16 is provided with a number of openings 26 and associated with each opening is a clamping member dirclosed more clearly in Figure 4. The vrespective clamping members 25 are hingedly connected at 27 to the drum 16. A spring 28 is connected to each of the clamping -members 25 and to the shaft 19. The springs 28 have a continuous tendency to hold the inner ends 29fagain51t the wheel 24 so that the various openings 26 will be `left unobstructed until the members 25 are moved to clamping position. It will be noted from Figure 4 that at one point the casing 1 is provided with an opening 30 which exposes the drum 16.v At the plucking station, that is, where the fowl is presented to the plucking means to be plucked, projecting sections 31" and 32 are arranged at the end of opening 30 so as to limit the opening and also prevent the fowl from being moved. against the drum 16 except at the proper point. members, 25 pass beneath the roller 33, which y roller is preferably provided with a rubber tire 34. As roller 33 is touching or almost touching the drum 16, the various clamping members' 25 will be swung over so that their ends 29 will come in contact with or almost come in contact with the beveled portions 35 and thereby pinch feathers or vanything else that may be projecting through the opening 26. Wheel 33 is pivotally mounted on the pin 36 which is journaled on the links 37, said links being connected by a bracket 38 and to which one end of the spring 39 is connected, the opposite end being connected at 40 to a sleeve 41. The inner ends of the links 37 are also pivotally connected at 42 to an extension 43 of sleeve 41. As sleeve 41 is rigidly secured to shaft 19, thetension of spring 39 may be varied by shifting arm 20 As the drum 16 rotates, the

Lenses and also the position of roller 33 in respect to the drum may be varied. Tf the feathers to be removed are small and thin, the parts are arranged substantially as shown in Figures 4 and 5. Tf large quantities and coman paratively heavy feathers are to be removed, the arm 2() is adjusted so as to move wheel 33 to cause a closing action of the clamping members 27 p sooner. This wilF cause the clamping members to clamp a less amount of feathers. v

In operation, the fowl is held in thel opening 30'so that the body will be near the drum 1'6. When the body is held in this position and fan 5 is rotated, a sufficient suction will be produced to cause the feathers to move in through the opening 26 as soon as the same ,comes opposite opening 30. The feathers remain projecting through 'this opening because the suction continues and when the drum moves a certain distance from the position shown in Figure 4 one of the clamping members 25 will swing down and clamp some of th'e feathers against thel part 35 and surrounding parts of the drum. This clamping action is caused by the pivoted end of the clamping member passing beneath roller 33. The roller 33 may. yield as it is pivotally mounted and held lin position by a spring. This will give a resilient gripping action and will cause a proper pull on the feathers gripped so that the same is pulled from the body while the body is resting against the drum or is held near the drum. As soon as one clamping member 25 has passed, another one will come into operation and the first one will gradually open as it passes the wheel 32. This gradual opening will release the pull of the feathers and the suction from fan 5 will cause the pulled feathers to quickly move through the chamber 3 into chamber 2 and from thence out the discharge member 4.

The device is intended particularly forl` pulling the feathers from fowls which have not been dipped in hot water. In preparing fowls for sale for Orthodox Hebrews,

the fowls must be killed in a certain manner and the feathers must be removed without ipping in hot water. I-Ieretofore, feathers have been removed by pulling by the hands of a workman and sometimes with the assistance of certain machines. In the present invention, a machine has been provided which will perform the pulling operation quickly and easily but the fowl must be held in place by a workman who must turn the fowl in different positions so as to expose the feathers to the openings 26 in drum 16. As an appreciable'suction is provided, not only will the feathers be removed butany dirt or foreign matter which is loose.

1t will be understood from the foregoing that a mechanism has been provided, realizing the objects -and advantages set forth, to-

lll

gether with other objects and advantages; and that changes may be made in the details of embodiment without departing from the principles' of the invention, and without sacrificing its chief advantages.
